Fewer is a word used in place of less when you want to sound like you majored in English at college, but will more likely end up making you look like a pompous asshole.

According to grammar nazis, there is a rule that “fewer” only modifies countable nouns and that “less” can only modify mass (uncountable) nouns. However, this "rule" is just one of the many superfluous decisions made in the 18th-century by pretentious douchbags who felt that certain things were mistakes simply because they didn't seem elegant or proper enough.

Despite what they say, the rule is not even commonly followed. This is probably because not everyone is anal retentive enough to quibble over arbitrary details that have little to do with how the language is actually understood and used by normal people.
